[0003] At present, there is no professional inspection equipment for the experiment of the front drive axle shaft. Usually, the half axle is assembled on the car for "8" curve road test, which can detect the work of the front drive axle under various normal and limit states. The status of the semi-axis prevents possible quality problems in the design verification, manufacturing, and assembly processes of the half-shaft. According to the original method of dismantling, analyzing, and discussing to make a judgment, not only the efficiency is low, but the work skills and experience of the analysis staff are high, and it can only be processed and corrected after the event, and cannot be prevented and verified in advance. , will bring more troubles and quality improvement lags to half shaft manufacturers

Embodiment Construction
[0021] see figure 1 , 2 It can be seen that this experimental device is a device installed on the test bench to simulate the "8" curve experiment of the car. It is mainly composed of a drive system, a resistance system and a base. On the pedestal, during inspection, one end of the front drive axle shaft 5 of the automobile is fixed on the drive system, and the other end is fixed on the resistance system. Specifically, see image 3 , the drive system includes a motor 1, a reducer 2, a coupling 3 and a first spline connection end 4, one end of the reducer 2 is connected to the motor 1 and the other end is connected to the first spline connection end 4 through a coupling, the first The spline connection end 4 is a connection port similar to the internal spline connection of the bevel gear, and is used to connect with the inner spherical cage installation end of the driving half shaft 5, thereby completely imitating the assembly method of the automobile differential and the half...

The invention discloses a working condition experimental device of an automotive front driving shaft. The working condition experimental device comprises a drive system, a resistance system, a base and a friction block, wherein the drive system comprises a drive device and a spline connection end connecting the drive device with the mounting end of a drive semi-shaft inner ball cage; and the resistance system is fixed on the base and is provided with a first spline connection end connected with the mounting end of the drive semi-shaft outer ball cage, and the friction block is contacted with a spindle of a second spline connection end. A model automobile eight-shaped curve road experiment of the device can be used for effectively detecting whether the problems of quality and design exist in the semi-shaft; and the whole device is simple in structure, convenient in assembly and fast and efficient in checking process, quality and efficiency of check on the drive semi-shaft are improved, and checking cost and working intensity and difficulty of checking operation are reduced.
Description
technical field [0001] The invention relates to an experimental device for a front drive shaft of an automobile; more specifically, it relates to an experimental device for simulating the working condition of the front drive shaft in a "8" curve road test. Background technique [0002] The front drive shaft of a car is a safety component on a car. If there is a serious quality problem, it may cause serious consequences of car crash. In order to avoid production quality defects, the quality of the half shaft must be checked during the design and manufacturing process. Carry out preventive verification, find out in advance the quality hidden dangers in the design or manufacturing process of the half shaft, and reduce the risk to the final consumer. Verify the quality defect, find out the problem and change it in time to minimize the risk; at the same time, it can also reproduce the fault of the drive shaft returned from the main engine factory to the half shaft manufacturer, s...
